Myoepithelial Carcinoma Arising in a Salivary Duct Cyst of the Parotid Gland: Case Presentation.

Cystic lesions observed in parotid glands are relatively rare and comprise 2-5% of all parotid primaries. A salivary duct cyst (SDC) is a true cyst representing 10% of all salivary gland cysts. The risk of malignant transformation of SDC's epithelium is extremely rare. In the literature, only three cases of carcinoma ex SDC of the parotid gland are described. This report presents the first in the literature case of myoepithelial carcinoma (MECA) arising from a parotid SDC. A 75-year-old male patient was referred to the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University in Cracow, Poland due to a cystic tumor arising from the right parotid gland. Superficial parotidectomy with facial nerve preservation was performed. Histological examination confirmed a rare case of MECA emerging from the SDC. The immunohistochemical profile of MECA ex SDC was presented. During 6 months of the follow-up, local recurrence or distant metastasis was not observed.

Feasibility of dpFAMM flap in tongue reconstruction after facial vessel ligation and radiotherapy-case presentation.

BACKGROUND: Salvage surgery with reconstruction of the second and next primary tongue cancer remains difficult, especially after earlier neck dissection and radiotherapy. In the current report, we describe the feasibility of the extended, double-pedicled facial artery musculomucosal (dpFAMM) flap in the reconstruction of the patient with second primary tongue squamous cell carcinoma, after facial vessel ligation and radiotherapy. CASE PRESENTATION: An 81-year-old female patient was operated on due to tongue squamous cell carcinoma (SCC) on the left side T3N1M0 in 2019. Bilateral selective neck dissection with tongue reconstruction was performed by island FAMM flap. The patient also suffered from synchronous mucinous breast carcinoma treated with tamoxifen. The second primary SCC of the tongue on the opposite (right) side was detected in 2020. The patient did not agree to surgical treatment; therefore, radiotherapy was performed. The local recurrence of the tongue cancer of the right side was treated surgically in 2021. Salvage surgery comprised hemiglossectomy and dpFAMM flap reconstruction with uneventful postoperative follow-up. CONCLUSIONS: This case presentation proved that dpFAMM flap can be used in salvage surgery and reconstruction even in patients after ligation of facial vessels, irradiation, and in the course of hormone therapy. The flap is easy to handle, has good vascularity, and comprises a predictable method of reconstruction, especially for patients with severe comorbidities.

Extended, Double-Pedicled Facial Artery Musculomucosal (dpFAMM) Flap in Tongue Reconstruction in Edentulous Patients: Preliminary Report and Flap Design.

Backgroundand Objectives: The reconstruction of tongue defects after cancer resection is challenging for reconstructive surgeons. The facial artery musculomucosal (FAMM) flap and the myomucosal buccinator flap (Bozola flap) are important tools in the reconstruction of intraoral defects. In this study, we describe the combination of both flaps-the extended, double-pedicled FAMM (dpFAMM) flap-and present clinical results of the reconstruction of moderate tongue defects in edentulous patients. Materials and Methods: a tongue defect, after squamous cell carcinoma excision, was reconstructed with the dpFAMM flap in 5 patients. Most of them received postoperative radiotherapy. Results: the healing process was uneventful in all patients. We did not observe flap necrosis or venous congestion. Tongue mobility, speech and swallowing were satisfactory. Conclusions: In conclusion, the dpFAMM flap is a good alternative in the reconstruction of moderate defects of the lateral part of the tongue. The flap is easy to harvest and has a good vascularity. This is a predictable method of reconstruction, especially for elderly patients with numerous comorbidities.

Miofrenuloplasty for Full Functional Tongue Release in Ankyloglossia in Adults and Adolescents-Preliminary Report and Step-by-Step Technique Showcase.

Background and Objectives: Ankyloglossia is a functional term describing limitations of motor activity of the tongue due to the embryological malformation of the lingual frenulum. The lingual frenulum has a complex, three-dimensional structure, it is not only a mucosal fold, which connects the ventral surface of the tongue and the floor of the mouth. Such knowledge forced us to develop more advanced techniques for tongue release in ankyloglossia. The aim of this study is to describe a novel, precise surgical technique for tongue release. Materials and Methods: Miofrenuloplasty was performed in six patients with impaired tongue movements due to anatomical limitations. All of them were prepared for surgery and evaluated after the procedure by a speech therapist. Results: The healing process was uneventful in all patients. We did not observe any major complications. Tongue mobility and neck muscle tension improved significantly in all cases. In one case, the speech improvement was minor. Conclusions: Miofrenuloplasty is an advanced, but effective and highly predictable procedure for full functional tongue release in cases caused by MFGG complex. It should be done by experienced surgeon.

Metastatic malignancies in the parotid gland: A retrospective study.

The aim of this study was to compare treatment modalities, pathological and clinical characteristics, and outcomes in patients with metastasis in a parotid gland. The medical records of 34 patients who received treatment for metastasis in the parotid gland over a twenty-year period were evaluated. Patients with head and neck cutaneous squamous cell carcinoma (HNcSCC) metastasis were retrospectively reclassified using the P/N and N1S3 staging system. Patients with neck metastasis showed a significantly poorer prognosis (P = 0.025). Univariate analysis also revealed that extent of parotidectomy and type of neck dissection did not influence recurrence free survival (RFS) and overall survival (OS). When comparing the usefulness of the P/N and S1N3 staging systems, a positive correlation was observed between the P stage and the N1S3 stage in both RFS and OS. The extent of parotidectomy and concomitant neck dissection is still under discussion. Total parotidectomy and modified radical neck dissection did not improve RFS and OS. N1S3 is a less complex classification and possesses a higher predictive value when compared to the P/N staging system.

Tumor-to-Tumor Metastasis: Dissemination of Cutaneous Squamous Cell Carcinoma Involving Parotid Warthin Tumor-Case Report.

Warthin tumors (WTs) are the second most common salivary gland tumors, most commonly found in the tail of the parotid gland. The lymphoid components of a WT may also serve as a site for tumor-to-tumor metastasis. This report describes the metastasis of cutaneous squamous cell carcinoma (cSCC) from the preauricular region to a parotid WT. A 68-year-old male patient was admitted to the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University in Cracow, Poland, with a two-year history of a growing, painless skin tumor of the right preauricular region. The patient was eligible for surgical treatment with elective neck dissection at the Va, III, II, I levels with parotidectomy and the excision of the cSCC. In the histopathological examination of the components of the surgical specimen beside the primary cutaneous squamous cell carcinoma (cSCC), a parotid WT was found; in the majority, it was occupied and destroyed by the metastatic cSCC and radically removed. After a tumor board consultation, due to the advanced stage (pT3N2b LVI2 PNI0 R0), with three intraparotid lymph node metastases and LVI2, the patient was authorized for postoperative radiotherapy. In conclusion, tumor-to-tumor metastasis is an extremely rare entity. Surgery is the standard of care for both WTs and head and neck cSCC. In most cases, metastasis into the parotid gland can be successfully treated with superficial parotidectomy with facial nerve preservation. Dissemination into the parotid gland requires elective neck dissection, as well as adjuvant treatment.

Risk Factors for Orbital Invasion in Malignant Eyelid Tumors, Is Orbital Exenteration Still Necessary?

Basal cell carcinoma is the most common malignant skin tumor of the eyelids in Caucasians, followed by squamous cell carcinoma and sebaceous gland carcinoma. The primary treatment for these tumors is radical excision. In cases where malignant eyelid tumors are advanced and have invaded the orbit, orbital exenteration is necessary. In this retrospective study, we aimed to determine the correlation between the risk of orbital infiltration and various factors like tumor location, size, histological type, and patient age. This study revealed that tumors in multiple regions increased the risk of orbital infiltration by 3.75 times. Tumors with a diameter of 21-30 mm raised the likelihood of requiring exenteration by 15.5 times compared to smaller tumors (up to 10 mm). Age was also associated with the likelihood of orbital invasion in periocular tumors. Interestingly, no correlation was found between the histological type of the tumor and the risk of orbital infiltration. Notably, the conjunctiva of the eyeball was the most commonly infiltrated orbital structure, followed by the orbital fat. Timely treatment and well-planned procedures are crucial for patients with malignant periocular skin tumors to avoid multiple reoperations and the potential need for orbital exenteration.

Giant Sublingual, Submental, and Lingual Dermoid Cyst Restricting Tongue Movement Undiagnosed for Several Years.

(1) Background: Dermoid cysts occurring in the sublingual space are uncommon, typically manifesting as painless, gradually enlarging masses, usually not exceeding 3 cm in diameter. These cysts can resemble various conditions due to their clinical presentation, with a relatively low occurrence rate in the oral cavity, accounting for about 1.6% of all dermoid cysts. (2) Methods: We present the case of a 17-year-old female with a giant dermoid cyst involving the submental, sublingual, and lingual areas, undiagnosed for several years. Diagnosis was achieved through MRI and fine-needle aspiration, leading to the decision for surgical removal through a cervical approach. (3) Results: The healing process was uneventful. From the first day post-surgery, the patient began myofunctional therapy, successfully regaining proper tongue functions. Throughout a 24-month follow-up, the patient remained symptom-free. (4) Conclusions: A cervical approach can successfully treat giant oral dermoid cysts involving submental, sublingual, and lingual spaces. Tongue function can be successfully regained through myofunctional therapy after surgical treatment.

"Air Sign" in Misdiagnosed Mandibular Fractures Based on CT and CBCT Evaluation.

BACKGROUND: Diagnostic errors constitute one of the reasons for the improper and often delayed treatment of mandibular fractures. The aim of this study was to present a series of cases involving undiagnosed concomitant secondary fractures in the mandibular body during preoperative diagnostics. Additionally, this study aimed to describe the "air sign" as an indirect indicator of a mandibular body fracture. METHODS: A retrospective analysis of CT/CBCT scans conducted before surgery was performed on patients misdiagnosed with a mandibular body fracture within a one-year period. RESULTS: Among the 75 patients who underwent surgical treatment for mandibular fractures, mandibular body fractures were missed in 3 cases (4%) before surgery. The analysis of CT/CBCT before surgery revealed the presence of an air collection, termed the "air sign", in the soft tissue adjacent to each misdiagnosed fracture of the mandibular body. CONCLUSIONS: The "air sign" in a CT/CBCT scan may serve as an additional indirect indication of a fracture in the mandibular body. Its presence should prompt the surgeon to conduct a more thorough clinical examination of the patient under general anesthesia after completing the ORIF procedure in order to rule-out additional fractures.

Could Obesity Be Related to the Increasing Incidence of Warthin Tumors?

Background: The number of patients diagnosed with Warthin tumors (WTs) has increased significantly in recent years. The association of obesity as measured by body mass index (BMI) with the incidence of WTs remains unclear. This retrospective study aims to compare the BMI and other clinical factors of patients diagnosed with WTs to those with other benign epithelial parotid gland tumors. Methods: Over a 24-year period, 465 cases of benign epithelial parotid gland tumors were treated in our department. Of these, 155 (33.3%) were diagnosed as WTs. The results of the WT group were compared with those of another benign epithelial parotid gland tumor. Results: The mean BMI of WT patients was 27.3, which was significantly higher than in other benign tumors (25.52; p < 0.001). Furthermore, statistically significant correlations were observed, including a higher incidence of WT in males (p < 0.001), in the elderly (p < 0.001), and in cigarette smokers (p < 0.001). Additionally, a higher prevalence of other head and neck cancers was confirmed in patients with WTs (p = 0.004); Conclusions: This study supports the multifactorial etiology of WT development. Among these factors, smoking, advanced age, and obesity have been identified as factors associated with the development of WT, which might be due to chronic inflammation linked to obesity.

Minimally Invasive Cervical Styloidectomy in Stylohyoid Syndrome (Eagle Syndrome).

(1) Background: Stylohyoid syndrome, known as classical Eagle Syndrome (cES), is characterized by calcification of the stylohyoid chain with numerous nonspecific symptoms, mainly pain. This study introduces minimally invasive cervical styloidectomy (MICS). (2) Methods: MICS was performed on sixty-five patients diagnosed with classical Eagle Syndrome. Patients underwent meticulous differential diagnosis. Surgical plans were established based on the findings from neck angioCT. (3) Results: The healing process was uneventful, without significant complications. The overall success rate was 97.0%, with a follow-up of a minimum of six months. In one case, the surgery did not yield the desired improvement. In one case, a partial relapse of symptoms was observed. (4) Conclusions: MICS is a straightforward and efficient surgical treatment technique for stylohyoid syndrome.

Surgical Treatment of Sublingual Gland Ranulas.

Introduction Ranulas are divided into oral (OR) and plunging (PR) and comprise the most common pathology of the sublingual gland. This study presents a case series of patients operated due to OR and PR within different type of modalities in a 1-year period. Objective The aim of this study is to determine the optimal surgical treatment of ranulas based on our results as well as in the literature review. Methods The medical charts of 7 patients with sublingual gland ranulas treated in 2020 were reviewed. Results The median age of the patients was 19. Three patients with OR were treated by marsupialization, micromarsupialization, and sublingual gland excision. Four patients with PR were operated via cervical approach in three cases and intraoral approach in one case. No recurrence was observed in 14 months of follow-up, on average. Conclusion Micromarsupialization should be consider as the primary treatment for OR. In case of recurrent OR and primary or recurrent PR, the best results might be obtained by radical excision of the sublingual gland, which can be performed without resection of the ranula sac with the intraoral approach.

Extraparotid Warthin Tumors Imitating Metastasis of Oral Cancers.

Introduction Extraparotid Warthin tumor (WT) is a very rare entity, especially when synchronous with oral cancer (OC). Objective The present study presents a case series of extraparotid WTs detected in the surgical specimen of patients treated for OC. Methods From 2007 to 2016, 336 patients were operated for OC in our institution. Neck dissection was performed in 306 patients. Results In the 306 patients operated for OC whose necks were dissected, unexpected WTs were observed in 4 surgical neck specimens. In 3 cases, extraparotid WTs were responsible for tumor, node, metastasis (TNM) overstaging before surgery. Conclusion Extraparotid WTs may be discovered during neck dissection in ∼ 1% of OC patients, and they may mimic neck metastasis, especially in positron-emission tomography/computed tomography (PET/CT) imaging.

Primary basaloid squamous cell carcinoma of the parotid gland mimicking metastasis of basal cell carcinoma of the contralateral periorbital region: case report.

Basaloid squamous cell carcinoma (BSCC) in the head and neck area is extremely rare. World Health Organization defined BSCC as a high-grade variant of squamous cell carcinoma composed both of basaloid and squamous components. Due to its histologic similarity to other parotid gland malignancies it can be easily misdiagnosed. We report first case of BSCC arising from parotid gland in Europe and second in the world literature. A 72-year-old female patient was referred to the Department of Cranio-Maxillofacial Surgery of the Jagiellonian University in Poland due to the tumor arising from the right parotid gland. Patient had history of multiple excisions of recurrent basal cell carcinoma (BCC) of the left periorbital region. We performed total parotidectomy with facial nerve preservation. Postoperative radiotherapy (PORT) was carried out, and the patient received 70 Gy in 30 fractions on the parotid gland area due to the fact that the tumor adhered to the facial nerve trunk and branches, additionally 60 Gy on the neck area in I, II and III levels. To distinguish the tumor of the parotid gland from the possible metastasis from BCC of the left medial canthal region previous histopathological slides were also reexamined and compared with histopathological examination of removed parotid gland tumor. Histological examination confirmed a rare case of BSCC arising from the parotid gland. 14 months of the follow up did not show local recurrence or distant metastasis.

Epidemiology of Primary Epithelial Salivary Gland Tumors in Southern Poland-A 26-Year, Clinicopathologic, Retrospective Analysis.

(1) Background: Epidemiological studies of epithelial salivary gland neoplasms are difficult to conduct effectively due to tumor rarity, histological heterogeneity, tumor location diversity, and a lack of national registries collecting data. This study presents 26 years of epidemiological data from a single institution in southern Poland that estimates incidence rates of primary epithelial salivary gland tumors. (2) Methods: The charts of 805 patients with epithelial salivary gland tumors were retrospectively reviewed. (3) Results: Pleomorphic adenomas occurred less frequently in elderly patients; however, Warthin tumors were more common (p < 0.001). Pediatric patients mainly suffered from mucoepidermoid carcinoma. The estimated crude and European age-standardized incidence rates of all primary epithelial salivary gland tumors were 6.7 and 6.02 per 100,000 population, respectively. The incidence rates of salivary gland tumors increased in recent years; however, this is attributed to an increase in benign tumors (p < 0.001). (4) Conclusions: The incidence of primary epithelial salivary gland tumors in southern Poland has increased over the past 26 years. This increase is attributed to a rise in the number of patients with benign tumors, particularly Warthin tumors in elderly patients. Moreover, the incidence of malignant salivary gland tumors appears to be higher in pediatric patients.

Turban Tumor Syndrome: In Search of a Gold Standard - A Case Report.

Turban tumor syndrome (TTS) is a rare condition characterized by predisposition to developing multiple adnexal tumors. It is the rare autosomal dominant genodermatosis that is associated with the mutation of the CYLD suppressor gene. We herein report rare TTS in an adult who suffered from numerous episodic ulcerations of the scalp tumors and frequent bleeding following a minor trauma. The plain radiograms of the skull excluded bone marrow infiltration, and no regional lymphadenopathy was noted. The patient underwent total scalp excision and split skin grafting under general anesthesia in a single-stage operation. Recovery was uneventful. No recurrence was observed during the 2-year follow-up. Due to a high recurrence rate and risk of neoplastic transformation, surgery should be considered as the gold standard.
